Diana Ross - Upside Down (SPare Extended Disco 12'' Mix)

Extended version from original multi-tracks.

The song was written by Bernard Edwards and Nile Rodgers (of the band Chic).
In a 2011 interview, Nile Rodgers said "Diana Ross was the first big star we ever worked with and we took it very seriously." Rodgers and Edwards interviewed her for several days. "This was the first time in her life somebody cared about who she was; what she was — everyone previously had treated her the way we had treated Sister Sledge — they got her in and said 'Sing this'. We (took a more personal approach)."
As would be widely reported later, their studio liaison with Ross was not a success. She disliked the results of their sessions and gave them specific remixing instructions; they made slight changes and suggested that if she still did not like them, she could get them remixed herself. Ross did so, reworking the whole album with Motown producer Russ Terrana to downplay the funk element and make her voice more prominent.
Rodgers and Edwards were initially furious, and considered having their production credit removed. They eventually decided to leave the track unedited, as the sound they used for Chic remained heavily influential on the album. The LP became a platinum-selling No. 1 that spent a year on the American chart. Ross left Motown soon afterwards for RCA.
